For Intel parts, yes. Oh no that's true; NVIDIA also did that with Fermi. Besides that, the vast majority of NDA lifts are the same date as the actual product hits retail...

Yeah, I was going with the last few NDAs that have happened.. especially the Fermi one. I kind of miss the majority (what with the recent trend) of the NDAs getting lifted and then you see the part in the store or on Newegg or something that day or the next day.

That is unless you were one of the minority that bought the top of the line Extreme Edition processors that were unlocked and may very well have been made of unobtainium based on the pricing structure of the Extreme Edition.
